20kW Hybrid Solar System – 22.32kW Solar + 30.72kWh / 40.96kWh ALP Battery Storage

22.32kW Solar Power with Your Choice of Growatt ALP Battery Storage

The ROCKSOLAR 20kW Hybrid Solar System combines two Growatt SPH10000TL-HU-US hybrid inverters, 36 Canadian Solar TOPBiHiKu6 CS6.2-66TB-620H 620W panels and your choice of Growatt ALP battery storage. The panels provide 22.32kW of rated solar capacity.

Choose Your ALP Battery Storage

Choose one battery option. Each ALP module provides 5.12kWh nominal and 4.6kWh usable energy. Usable energy is before inverter losses. The eight-module option offers more stored energy for longer runtime at the same load.

Solar Power by Day. Backup When You Need It.

Use solar power during the day and stored battery energy at night to reduce the electricity you buy from the grid. During an outage, the system can keep selected lights and appliances running through a properly installed backup connection. It also supports charging from a compatible generator.

Choose eight ALP battery modules for longer backup time at the same power use. Backup coverage and runtime depend on your battery charge and household demand.

Canadian Solar 620W Panel Highlights

• 22.32kW solar array: 36 × 620W panels, rated at standard test conditions.
• N-type TOPCon technology: TOPBiHiKu6 CS6.2-66TB-620H modules with 23.0% front-side efficiency.
• Bifacial generation: Rear-side production depends on reflected light and installation conditions.
• Low power temperature coefficient: -0.29%/°C helps limit power loss as cell temperature rises.
• Dual-glass construction: 2.0mm front and rear glass with an anodized aluminium alloy frame.
• Panel dimensions: 2382 × 1134 × 40mm; 33.4kg per panel.

Growatt ALP Battery Highlights

• LiFePO4 battery chemistry
• Modular design in two stacks of three or four modules
• IP66 / NEMA Type 4X battery enclosure
• Built-in BMS monitoring and CAN communication
• 51.2V nominal battery voltage

Split-Phase or Three-Phase Power

The two inverters provide 20kW of combined rated inverter capacity in a 120/240V split-phase installation. Growatt also documents a two-inverter 120/208V three-phase configuration for compatible equipment. Three-phase requires a separate installation design and commissioning. Confirm available power on each phase and motor-starting requirements; the combined inverter rating does not establish 20kW of balanced three-phase capacity.
